- W2347217412 abstract "Music signal frequency covers 20Hz to 20kHz range, sound system in order to restore their high quality, often two music signal can be divided into high and low frequency or high, medium and low three frequency respectively to two speakers or three points frequency speakers to replay. If the frequency divider is located in the power amplifier, we call it electronic frequency division system, if the frequency divider after power amplifier, we call it a power frequency division system. Two kinds of system from the performance of each has his strong point, but from the high fidelity perspective, the performance of the electronic frequency division system is superior to power frequency division system. If dividing grinding a set of electronic sound system, in addition to the high quality of assembly design levels after power amplifier, the former level frequency divider design it is very important. This article is based on the actual production experience and data, butterworth 2 order frequency divider and 2 order 3 frequency divider in the use of sound system put forward their own opinions." @default.
